T0 (tZZ whom, it may concern.-

Be it known that I, J OSEPH HALL, a subject of the Queen of GreatBritain, residing at Leeds, in the county of York, England, haveinvented new and useful Improvements in Leather-D ressing Machines, (forwhich I h ave obtain ed a patent i n Great Britain, No. 23,720, datedDecember 6, 1894,) of which the following is a specification.

My invention consists in machinery for shaving, slicking, whitening,buffing, scouring, setting, flatting, slating, fleshing, and scuddingskins, leather, and analogous substances.

The object of my invention is to provide improved machinery for thepurposes aforesaid, which can be carried out by simply changing thecutters or cylinders and which is specially applicable for shaving andleveling skins, by which a skin can be shaved and leveled at onecontinuous operation, or half of the skin can be so treated and the skinand machine then reversed, so as to shave and level the other half, animportant feature of my said invention being that the action of themachine can be reversed automatically or by hand.

In the drawings, Figure 1 is a side elevation of machine according to myinvention. Fig. 1 is an end view of portions of the devices whichactuate the driving+roll, portions of one of the side frames and of thebelt-pulley 10 being shown broken away. Fig. 2 is an enlarged detailview of feeding arrangement. Fig. 3 is a front elevation of Fig. 1. Fig.i is a plan view.

A is the driving-shaft of the machine, journaled in bearings B on theside frames 0 and provided with a driving-pulley N.

A is a rotary cutter, of approved construclion, secured on the shaft Abetween the inner side frames.

D is an emery grinding-roll for keeping the cutter sharp. Thegrinding-roll D is revolved in contact with the cutter by means of abelt D driven from a belt-pulley 10. The pulley 10 is secured on a shaftD and is driven from any approved source of power. The shaft D isjournaled in two similar vertically and longitudinally slidable bearings11, carried by the side frames (3.

D are two similar screws operating to adjust the bearings 11 vertically,and D are two similar screws operating to adjust the bearings 11longitudinally. The screws D are journaled in brackets D and engage withthe lugs D on the bearin gs 11. The brackets D project fromlongitudinally-slidable bearin gs 12, in which the grindingroll shaft 13is journaled. The bearings 11 and 12 have flanges which straddle thetops of the inner side frames (J. The screws D engage with the flangesat the tops of the frames and raise the bearings 11 when screwed upward.The bearings 12 are not adjustable vertically. Similar bearings andmeans for adjusting them are provided on each side of the machine.

The position of the grinding-roll is adj usted by means of two similarscrews D journaled in blocks 13, secured to the side frames and engagingwith the brackets D. A wormwheel 14 is secured on each screw D and isrevolved by means of a hand-wheel D and a worm D of approvedconstruction. This arrangement of parts not only permits thegrinding-roll to be adjusted to the cutter and simultaneously slidesalong the bearin gs 11, so that the belt is kept at a uniform tension,but it permits the tension-of the belt to be adjusted separately by thescrews D without affecting the adjustment of the grinding-roll.

G is a driving-roller covered with indiarubber and mounted on the shaftH.

H are two similar cheeks pivoted on the shaft H.

H are links pivoted together and connected with the cheeks H and to arock-shaft H journaled in the side frames.

H is a hand-lever secured on the rock-shaf t H and operating to rock thesaid cheeks.

G and G are the two lower guide-rolls, journaled in the cheeks H. Theroll G is arranged under the cutter A, and the roll G is arranged at alittle distance in front thereof.

G is the feed-board in front of the roll G.

G' is a feed-roll arranged over the roll G. The roll G runs in the sideframes and is provided with any approved means for adjusting itvertically, so that it may bear with more or less pressure on the hide.

The hide is passed from the feed-board between the rolls G and G andbetween the roll G and the cutter A. \Vhen the motion of the feed-rollsis reversed, the hide is carried back again. I

E is a guide-plate carried by a bar A which projectsthrough holes in theside frames and is supported by two similar arms J pivoted on thecutter-shaft A. The rear edge of the plate E can be depressed to pressthe hide on the roll G A second guide-plate E can be arranged behind thecutter, if desired.

The guide-plate E is raised and lowered by means of rods J, which areconnected to a counterbalanced foot-lever J by a shaft J journaled inthe side frames.

The feed-rollers are revolved first in one direction and then in theother by means of two belt-pulleys at and y, secured on the shaft A.

is a shaft journalcd in the lower parts of the side frames. I I

N and N are loose pulleys journaled on the shaft N and N and N are fastpulleys secured on the shaft N".

N is an open belt passing over the pulleys and N N and N is a crossedbelt passing over the pulleys y and N N N is abelt-shifter of approvedconstruction for operating the belt N and N is a similar belt-shifterfor opcratin g the belt N 1 is a toothed pinion secured on the shaft Nand gearing into a toothed wheel 1", se-

cured on a shaft N journaled in the side frames.

P is a toothed pinion secured on the shaft II of the roller G andoperating to revolve it.

The wheel P gears into a pinion P secured on the end of the shaft P onthe other side of the machine from the belt-shifters.

P is a toothed wheel journaled on a pin projecting from the adjacentside frame and gearing into the wheel P P is a toothed wheel secured onthe shaft of the feed-roll G and gearing into the wheel P so that thesaid roll is revolved.

The feed-rolls G and G are revolved by frictional contact with theroller G.

P is a toothed wheel gearing into the toothed wheel P and j ournaled ona pin projecting from the adjacent side frame.

N is a toothed wheel gearing into the wheel P and j on rnaled on theshaft N The wheel N is provided with projections N for operating thebelt-shifters in any approved manner, so that the. direction of motionof the feed-rolls and of the roller G can be changed automatically. Thebeltshifters may, however, be operated by hand. The belt-shifter N isconnected to a'slidable bar N extending across the machine, and thebelt-shifter 'N is connected with a slidable bar N in .t

similar manner. A bar 0 is also operativeiv connected with thebelt-shifter bar N anu operates a lever 0 secured on a vertical shaft 0which is journaled in suitable bearings. A lever O is secured on theshaft 0 and engageswith a slidable bar 0, whichextends across themachine and is provided with it tappet 0 as shown in Fig. 2 This tappetengages with a projection 0 on one of the cheeks H and raises theguide-plate when the hide is to be fed in. The other side of the machineis provided with a similar bar 0 for operating a similar projection onthe other cheek, and the two bars 0 are operativeiv coupled together bya cross-shaft and 1evers 21.

hat Iclaim is 1. In a leather-working machine, the combination, with arevoluble cutter, of a grinding-roll 'mounted in slidable bearingsprovided with brackets D, stationary blocks'lii". screws D journaled inthe said blocks and engaging with the brackets D5, means for re volvingthe said screws, a belt-pulley 10, slidable bearings 11 supporting saidpulley and provided with lugs D abelt passing over the pulley 10 anddriving the grinding-roll, and revoluble screws D journaled in thebrackets D and engaging with the lugs Dhwhereov the belt-pulley can beadjusted simultaneously with the grinding-roll or separately,substantially as set forth.

2. In a leather-working machine, the combination, with a revolublecutter, and a roller G; of two feed-rolls G G driven by friction fromthe roller G, said roll G being under the cutter, a feed-roll G over theroll G, a feedboard G cheeks pivoted concentric with the roller G andsupporting the rolls G G and the board G means for oscillating the saidcheeks, arms J pivoted concentric with the cutter and provided withmeans for oscillating them, a bar A carried by the said arms. aguide-plate E carried by the said bar and arranged over the roll Gdriving mechanism for revolving the cutter continuously in onedirection, and driving mechanism operating to revolve the roller G andfeed-roll G first in one direction and then in the opposite iirection,substantially as set forth.
